Definitions
- Turbine ring assembly made of ceramic matrix composite material.
- the invention relates to a turbine ring assembly for a turbomachine, the assembly comprising a plurality of one-piece ceramic matrix composite (CMC) ring sectors and a ring support structure.
- CMC ceramic matrix composite
- the field of application of the invention is in particular that of aeronautical gas turbine engines.
- the invention is however applicable to other turbomachines, for example industrial turbines.
- CMC Composite matrix ceramic
- WO 2010/103213 discloses a turbine ring assembly for a turbomachine, comprising a plurality of one-piece CMC ring sectors, each ring sector having a first annular base portion with an inner face defining the inner face of the turbine ring and an outer face from which extend two leg portions whose ends are engaged in housings of the ring carrier structure, the ring sectors. having a substantially ⁇ -shaped section and the ends of the tabs are held without radial clearance by the ring support structure.
- the ring support structure is metallic and is close to the flow path of hot gases so that it undergoes a significant increase in temperature.
- the Metal structures are therefore likely to be damaged by the high temperature of the vein gases.
- the CMC ring sectors have a very low allowable stress, high stiffness, and much less expansion than the metal ring support structure. Therefore, since the ring sectors are maintained without radial clearance in the aforementioned document, they are weakened as soon as they are subjected to very high temperatures because of the mechanical stresses imposed by the difference of expansion with the structure of ring support.
- the main object of the present invention is thus to overcome such disadvantages by providing a turbine ring assembly which compensates for the differential expansion between the CMC ring sectors and the metal ring support structure, protecting the structure ring support of hot gases from the vein and reducing the stresses imposed on the high temperature ring sectors.
- a turbine ring assembly comprising a plurality of ring sectors, each ring sector being made of a single piece of ceramic matrix composite material and to be mounted on a support structure of metal ring, the ring support structure comprising two tabs extending radially towards a flow stream of the gas stream, each ring sector having a first annular base portion with a radially inner face defining the inner face of the ring; turbine ring and an outer face from which extend two leg portions, the ring sectors having a substantially ⁇ -shaped section.
- the tabs of each ring sector axially grip the tabs of the ring support structure with cold contact between the tabs of the ring support structure and the tabs of each ring sector.
- each ring sector being held to the ring support structure by means of pins passing right through holes in the tabs of each ring sector and lodged in the legs of the ring. the ring support structure, the holes of the legs of each ring sector having a size greater than the diameter of the pins of to form a cold game between the ring sector and the ring support structure.
- cold clearance is meant when the turbomachine is not in operation. Specifically, the metal expanding more than the CMC, the holes formed in the legs of each ring sector being larger in size than the pins, they compensate for this expansion and to ensure that the ring sectors in CMC are effectively maintained without being too strongly constrained at high temperature.
- the differential expansion becomes advantageous because it provides the seal between each ring sector and the ring support structure.
- the metal tabs of the ring support structure will, when the turbomachine is in operation, expand axially (that is to say in the flow direction of the gas flow in the turbomachine) and exert a slight pressure on the legs of each ring sector which surround them, thus ensuring this seal.
- the ring support structure has two tabs that can be separated by a void space, each of these tabs has a certain flexibility that allows it to withstand the constraints imposed back by the CMC ring sector. which is more rigid, without it breaking.
- the ring support structure being sealed with the tabs of each CMC ring sector, it is protected from the hot gases of the vein since the CMC is heat resistant and forms a thermal barrier. This arrangement makes it possible to reduce the cooling of the ring support structure and thus to reduce the consumption of the motor due to the withdrawal of air necessary to effect this cooling.
- At least one tab of each ring sector has at least one elongated hole extending in a circumferential direction so as to form a clearance between the ring sector and the ring support structure.
- the presence of these oblong holes extending in a circumferential direction advantageously makes it possible to compensate for the expansion of the ring support structure in the circumferential direction.
- At least one tab of each ring sector has at least one elongated hole extending in a radial direction so as to form a clearance between the ring sector and the ring support structure.
- the oblong holes extending in a radial direction compensate the expansion of the ring support structure in the radial direction.
- the pressure difference between the outer face and the inner face of the ring sectors keeps them pressed against the flow vein.
- the tabs of each ring sector each comprise at least one oblong hole extending in a radial direction and at least two oblong holes extending in a circumferential direction so as to form a clearance between the ring sector and the ring support structure.
- the expansion of the ring support structure is thus compensated in the two directions of stress (radial and circumferential), which advantageously limits the fragility of each ring sector and allows a more effective maintenance of these.
- a tab of each ring sector has at least two oblong holes extending in one circumferential direction, and the other leg of each ring sector has at least one oblong hole. extending in a radial direction so as to form a clearance between the ring sector and the ring support structure.
- each peg has a head at an end opposite to that housed in the lug of the ring support structure.
- the presence of these heads on the pins facilitates the assembly and disassembly of the ring sectors on the ring support structure.
- the pins are housed in non-through holes formed in the ring support structure.
- the pins are held axially thanks to the stop formed by the holes opening into the ring support structure which ensures an effective maintenance of the ring sectors, while avoiding forming a passage for the hot gases of the vein towards the inside of the ring support structure.
- each ring sector can be covered with an abradable coating.
- the pions are preferably made of metal. In this way, they will be able to lodge in the ring support structure without significant play and be able to expand in the same manner as the ring support structure, while maintaining the CMC ring sectors.
- the invention also relates to a turbomachine comprising a set of ring sectors such as that described above. Brief description of the drawings
